Heya,
After seeing your post it got me talking to a few of my MFP friends and although we feel we are no-where near fit and ready for 2014 we have started a group for 2015 if you want to join? We have only just done this so its looking a little sparse and there arent many members atm.

Good luck with getting a team together
